In DoF you'll start with a simple village and build up to a stronghold with several layers of walls and a keep inside, you can see it in the screenshots too. It's the "classical" castle set up and a well known fact about DoF although different races' strongholds will differ in types and strength of available defenses.

Ah ok,

and how long would you say it would take to make it up to castle style.

Also, you said theres no micro-management somewhere.... maybe the video.

Does that mean the city/castle/town builds houses itself and stuff and you place the walls.
